The Effect of Fibre Blend on Comfort Characteristics of Elastic Knitted Fabrics Used for Pressure Garments

Development of V-Shaped Compression Socks on Conventional Socks Knitting Machine

“…This difference in widths is due to machine adjustments and varying linear densities of the spandex yarns. Fernando et al studied that by increasing the tension of the spandex yarn and loop length (degree of needles) of rigid material, there is an increase in weight per unit area and thickness, which ultimately affects the width of socks at ankle and calf according to machine adjustments [9].…”

“…The loop-forming yarns like body yarn (spun/filament) and plated yarn (air covered) form the loops together. Inlaid yarn (double covered yarn) is integrated into each loop of every course [3,[8][9][10]. Various studies exist in which different fiber/yarn types (varying spandex yarn linear densities and compositions) [2,[9][10][11], different types of spun/ core spun yarns of different linear densities [7], different kind of inlaid yarn, [2] varying tension by increasing or decreasing the ultra-feeder yarn tensions into the knitting machine and different fabric structures (manufactured and readymade), [7] different sizes and shapes of the substrate (cylindrical tube or wooden leg) were used to exert maximum pressure at ankle and optimum graduation [4].…”

But there is no study in which the shape of the socks is changed by figuring out the machine adjustments and using different linear densities of spandex yarn on the conventional socks manufacturing machine.…”

Effect of elastane linear density on compression pressure of V-shaped compression socks

“…As per international classification of pressure exertion intensity, it is classified as CCL1 (light) up to 20 mm Hg; CCLII (moderate) 20-30 mmHg and CCLIII firm compression (30-40 mmHg). These levels of pressure exertion are recommended medically to treat circulatory and vascular medical conditions as well for tired, sore, swollen, or aching legs [3][4][5][6]. Theoretically, the amount of pressure in the circumferential direction of leg depends on the radius (R) of leg and reversal force T (N).…”
